STRAW-BOARD-L SPECIFICATION forming part of Letters Application filed April 3, 1886.

To all whom it may concern:

Be it known that I, ARNOLD W. SOHLIOHTE, of the city, county, and State of New York, have invented a new and Improved Straw- Board-Lining Machine, of which the following is a full, clear, and exact description.

My invention relates to the construction of a machine designed to line or face sheets of card-board with any style of white or colored paper; and the invention consists, essentially, of a mechanism by the use of which the operator is able to sever the web which constitutes the lini n g material between each sheet of board after the lining material has been pasted and pressed to place upon the board, the parts being so arranged that sheets of board of varyingsize may be used without in any way changing the adjustment of the machine.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a view illustrating the general arrangement of the lining-machine, the upper portion of the web-severing mechanism. being shown in section to disclose the construction of the parts. Fig. 2 is a view of the looselyconstructed and pivotally-mounted frame carrying the web-severing mechanism, representing the parts as they appear when the knife is in its raised position. Fig. 3 is a similar view illustrating the position of the parts after the knife has been drawn down. Fig. c is a sectional plan view of a portion of the pivotallymounted frame, the view being taken on line x of Fig. 2.

One of the greatest difficulties encountered in lining straw-board is due to the fact that the boards are far from being of uniform size or shape, and consequently most of the machines constructed to sever the web between the sheets are necessarily made so that there will be quite a space between the boards as they are fed in to the rollers, and consequently quite a loss of paper, as well as an additional amount of work due to the trimming up of the sheets after they have left the machine. Vith my improved form of lining-machine, however, I am. able to introduce the sheets so that there is but very little space between the meeting edges of the sheets, and the web having been severed the lined sheet requires no fur ther manipulation.

INING MACHINE.

Patent No.350,272, dated October 5, 1886.

Serial No. 197,615. No model.)

In constructing the machine I provide a paste-trough, A, in which there is arranged a paste-distributing roller, (1, and directly above this paste-roller a there is a guiding-roll, Z), other guiding-rollers, as c 0, being arranged in any convenient position, for a purpose to be hereinafter explained. The pressure-rollers d c are arranged directly in front of the feedtable B, and just beyond these pressure-rollers there is a loosely-constructed frame, 0, in which there is mounted a second frame, D, carrying asevering-knife, E, preferably formed with a serrated edge, as shown, although any form of knife that would act to sever the web would answer my purpose.

The frame D is guided by the longitudinal cross-strips ff of the frame 0, and also by the extending ends of its lower erossstri p, ,which D to ride against the faces of the vertical strips h h. The frame 0 is pivotally connected to brackets fixed to the floor of the apart ment in which the machine is located; or the brackets to which the frame is connected could be carried by any appropriate framework.

The frame D is normally held in. the posi tion shown in Fig. 2 by spiral springs it, one end of said springs being secured to the frame 0, while the other ends are secured to the frame D, or to pins projecting therefrom.

To the lower bar, 9, I secure a cord, j, which passes downward overa sheave, j, and then upward toward the right of the machine over a guiding-sheave, 7d, and is finally secured to a lever, F, that is mounted to swing upon the point G; and it will be seen that by throwing the lever in the direction of the arrow the frame D will be pulled down to the position shown in Fig. 3.

As best shown in Fig. 4, the central crossbar of the frame D is formed with two recesses or openings, 21, and in these recesses I arrange the upper ends of the upper links, m, of two or more to ggle-levers, M M, the lower links, m, of which are pivotally connected to the lower crossbar f of the frame 0, the central joints of the toggle-levers being connected bya connecting-link, N. Upon the forward face of the lower cross-bar f, I arrange a guidingsheave, 0, and over this sheave o, I pass a cord, 9, one end of which is fixed to the rod N ,while the other end is secured to the lower cross-bar,

projects outward from each side of the frame g, of the frame D. The upper ends of the links to m carry stops s s, which project upward just in front of the severing-knife E. A second cord, q, is fixed to the rod or link N and passes over a sheave, 0', carried by the frame 0, and is carried backward to a fixed point, q. The frame 0 is normally held up close against the rollers d c by the action of a weight, H, which is connected to the frame 0 by means of a cord, 1), which passes over a sheave, a, as shown in Fi 1.

The machine is preferably driven by a crank-arm that is connected to the shaft of the roller (1, the paste-roll a being in turn driven by appropriate connecting-gearing.

The web of paper with which the sheets of straw-board are to be lined is taken from a roll, K, that is mounted in any convenientposition, and carried downward beneath the guiding-roll b, which runs in close contact with the pastedistributing roll a, by which paste is distributed upon the face of the web L. The web is then carried to the guide'rolls c c, which act to thoroughly distribute the paste upon the surface of the web, and from the guide-rolls c the web is carried around the roller (1 and into the bite of the rollers d c, the roller ebeing held in yielding contact with the roller d. After the web is in the bite of the rolls (1 and e the sheets of card-board may be fed in from the table B, and in being carried forward will strike against the stops as, and thus carry the frames 0 D forward in the direction of the arrow. As soon as the frame starts forward, as described, the attendant grasps the lever F and pulls it toward him-that is, he pulls thelever in the direction of the arrow shown in connection therewith, and this movement of the lever will. draw down the frame 0 to the position shown in Fig. 3, thus severing the web; but as the frame (J is drawn down the cord 1) is also drawn down, and the togglelevers carrying the stops 8 s are moved to the position shown in Fig. 3, thus permit ting the leading end of the sheet to pass forward beyond the stops and over guides to the guiding-rollstt, from which rolls the sheets are taken and piled by hand. Immediately after throwing the lever to depress the knife E the attendant releases the lever, and the weight H will act to d 'aw the frames back against the rollers d and e, and as the frames so move back the cord will draw the toggle levers to the position shown in Fig. 2.

From the construction. described it will be seen that immediately upon the release of the lever F the frame D will return to'its elevated position, and thus raise the end of the sheet, which has become somewhat depressed in the operation of severing the web, so that the said end will not catch against the horizontal strip f of the frame, and it will be seen that this return of the frame D takes place before the stops .5- s are returned to their raised position. In order that the operation of the machine need not be interrupted if the attendant should fail to pull the lever F in time to draw down the stops 8 s, I have provided a second cord, at, that is fixed to the connecting-link N, passed about the sheave v, and carried forward to a fixed point beneath the feed-table, there bein g a certain amount of slack in the cord which is not taken up until after the swingingframes have passed the position to which they would ordinarily be moved. In orderthat theknife E may be closed after each operation, I ar range a strip, 1), that is carried by the frame 0 close up against the face of the knife.

As before stated, the frame 0 is loosely put together, the idea being to permit a certain amount of yielding of the frame at either side should the sheet of strawlioard be uneven, so that the stops upon one side are met before those on the other side come :in ccmtact with the leading edge of the board.

Having thus fully described my invention, what I claim as new, and desi re to secure by Letters Patent, is-- 1. In a straw -board lining machine, the combination, with a paste-distributing apparatus and pressingrolls, of a websevering mechanism, substantially as described, that is carried by a yieldinglymounted frame arranged in front of the pressing-rolls, substair tially as described.

2. In a straw boardlining machine, the combination, with a web and board associat ing mechanism, substantially as described, of a pivotallymonnted frame, '3, a slidingframe, D, carrying a web-severing knife, E, movable stops 5, a weight, If, connected to the pivotally-mounted frame, a lever, and connections whereby the knife-carrying frame may be depressed, substantially as described.

3. In a straw -board -liniug machine, the combination, with a web and strawboard associating mechanism, of a pivotally-mounted frameand its weight H, a sliding frame, 1), carried by the pivotally-mounted frame, a knife, E, carried by the frame D, stops as, carried by the upper links of toggle-levers M, a connecting-link, N, and a cord, 1, substantially as described.

4. In a straw board lining machine, the combination, with a web and straw board associating mechanism, of a frame pivotally mounted behind the associating-rolls and normally held against said rolls by a weight, 1 1, a sliding frame mounted on said pivotallymounted frame, a knife, E, carried by the sliding frame, stops .9, carried by the upper links of toggle-levers M, the lower links of said tog gle-levers being connected to a cross bar of the pivotally mounted frame, cords p and q, arranged substantially as described, a cord, j, and lover F, all substantially as described.
